IMPROVEMENT IN GAS-REGULATORS.

To all whom it may concern:

Be it known that I, JOSEPH S. WOOD, of the city and county ofPhiladelphia, and State of Pennsylvania, have invented a new andImproved Gas-Regulator; and I do hereby declare the following is a fulland exact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

The object of my invention is to make a gas regnlator which shallequalize the pressure of gas through the various burners in a house orbuilding, so that whatever the number of burners in use the pressurethrough each will be nearly constant.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

Figure l is a cross-section. Fig. 2 is a horizontal section through w 3Fig. 3 is a longitudinal section through the receiver.

Similar letters in each refer to the same parts.

I construct my regulator of a tin vessel, A, which is filled with waterup to the outlet B. G is an air-tight receiver, open to the water atthebottom 0. Two air'tight chambers, I), are soldered to it to give thereceiver the requisite buoyancy in the water. These chamhers had betterbe made too large than too small. The receiver can then be weighted toits proper buoyancy for the pressure of gas required. V

E and F are two bent pipes fastened securely inside the vessel A. Theend E is connected to the pipe from the meter.- The short arm Eterminates above the water-level in the receiver 0. The end F isconnected to the pipe leading to the gasburners, and the short arm Fterminates above the water-line under the receiver 0. These pipes mayeither be bent at the bottom or screwed into a halfturn. I prefer toscrew them into a casting, G G, which is soldered inside the bottom ofthe receiver A, and holds the pipe securely in place. The arm E has aring, 9, screwed on, having in it a small central opening, a. In thishole, and suspended to the receiver 0, is hung a valve, h, in the formof a conical plug. K. is a screwed rod passing airtight through thereceiver 0, and by which the position of the valve h may be adjusted.

The action of the regulator is this: The gas from the meter passes downpipe E, up E through opening n'into the receiver 0, then down F and up Fto the burners. The pressure of gas in the pipe F F 2 and the receiverGis always the same. Suppose it is required to have a constant pressureof two inches of water to the burners, and the main is generally at fourinches pressure, the receiver G is so weighted that as soon as thepressure in it gets above two inches it rises and lifts with it thevalve h. As this valve h rises it contracts the opening a, and thereceiver 0 rises to just that point at which the opening a will admitsufficient gas to maintain the pressure at two inches in the pipe F.

The receiver 0 is guided in its up-and-down motion by rings at slidingupon the pipes E and F.

I do not claim the inverted receiver-O, or

stantially as described.

3. The combination of the vessel A, pipes E and F, receiver G, and valveh, arranged and operating substantially as described.
